# Bootstrap Component Control

Add a control that has BootstrapVue Component library support.

ProcessMaker Platform supports adding [BootstrapVue](https://bootstrap-vue.org/docs) components in [Forms](/v1/docs/form-task). Use BootstrapVue to display responsive, mobile-first, and ARIA-accessible forms projects on the Web.

> This control is only available for Form-type Screens. See [Screen Types](/v1/docs/screens#screen-types).

## Add the Control to a Screen

**Permissions**

Your user account or group membership must have the following permissions to design a Screen unless your user account has the **Make this user a Super Admin** setting selected:

- Screens: Edit Screens
- Screens: View Screens

See the [Screens](/v1/docs/permission-descriptions-for-users-and-groups#screens) permissions or ask your Administrator for assistance.

Follow these steps to add this control to the [Screen](/v1/docs/screens):

1. [Create a new Form-type Screen](/v1/docs/create-a-new-screen) or [edit an existing one](/v1/docs/manage-screens#edit-a-screen).
2. From the Controls Menu on the left, expand the **Advanced** category, and then locate the **Bootstrap Component** icon ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/2b1a8d8b-ed69-4a35-88e0-c090b5caa211.png).
3. Drag and drop the control to the Screen Builder canvas. Existing controls in the Screen will adjust positioning based on where you drag the control.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/36b89b07-5044-4c36-94c8-a838919a55d3.png)
4. Configure the Bootstrap Component control. See [Settings](/v1/docs/bootstrap-component-control#settings).
5. Validate that the control is configured correctly. See [Validate Your Screen](/v1/docs/validate-and-publish-a-screen#validate-a-processmaker-screen).

## Settings

The Image control has the following panels that contain settings:

- [**Variable** panel](/v1/docs/bootstrap-component-control#variable-panel-settings)
- [**Configuration** panel](/v1/docs/bootstrap-component-control#configuration-panel-settings)
- [**Advanced** panel](/v1/docs/bootstrap-component-control#advanced-panel-settings)

### Variable Panel Settings

Expand the **Variable** panel from the Properties Panel on the right to configure the following properties:

#### Variable Name

Edit the default **Variable Name** setting value for this control if necessary. The **Variable Name** setting value represents data in this control during Requests. Ensure that the **Variable Name** setting value is a unique name from other controls in this [Screen](/v1/docs/screens) and contains at least one letter. This is a required setting.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/2bcf24e1-d0dd-402a-9bc6-953e049b75b5.png)

Use the **Variable Name** setting value in the following ways:

- Reference this control by its **Variable Name** setting's value. The **Data Preview** panel in Preview mode represents the state of the Bootstrap Component control using its **Variable Name** value in the Request's JSON data model.
- Reference this control's value in a different Screen Builder control. To do so, use [mustache syntax](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/mustache.5.html) and reference this control's **Variable Name** value in the target control. Example: `{{ b_form_component_1 }}`.
- Reference this value in [**Visibility Rule** setting expressions](/v1/docs/bootstrap-component-control#visibility-rule).

See [best practices](/v1/docs/screen-design-best-practices#naming-request-variables-for-screen-controls) when editing a Request variable name.

#### Label

Edit the default **label** that displays for this control if necessary. **New Bootstrap Component** is the default value.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/30c09f57-df97-411a-955e-159034ecb755.png)

#### Validation Rules

Enter the validation rule(s) the Request participant must comply with to properly enter a valid value into this control. This setting has no default value. If there are no configured validation rules the following message displays: **No validation rule(s)**. See [Validation Rules for "Validation" Control Settings](/v1/docs/validation-rules-for-screen-controls).

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/ce88806b-72a8-4aa6-a04c-c1fa4c350533.png)

1. Access the [**Variable** panel for this control](/v1/docs/bootstrap-component-control#variable-panel-settings) while in Design mode, and then locate the **Validation Rules** setting.
2. Click the **Add Rule** button. The **Select** drop-down menu displays.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/0d1949fb-8d22-41fd-afc9-ec0c171d2e98.png)
3. Select the rule that this control validates against.
4. Click **Save**. Parameters for the selected rule display. Parameter settings display which ones are required to properly configure the rule.
5. Enter the parameter settings that this control uses to validate against. See [Validation Rule Settings](/v1/docs/validation-rules-for-screen-controls#validation-rule-settings), and then locate the validation rule for its parameters.

Follow these steps to edit a validation rule for this control:

1. Access the [**Variable** panel for this control](/v1/docs/bootstrap-component-control#variable-panel-settings) while in Design mode, and then locate the **Validation Rules** setting.
2. Click the **Edit** icon![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/469ab28d-bfce-47a5-bc18-3d8f6c4b4a1b.png)for the validation rule to edit if that rule can be edited. Validation rules that do not have parameters cannot be edited. The parameter settings for that validation rule displays.
3. Edit the parameter settings that this control uses to validate against. See [Validation Rule Settings](/v1/docs/validation-rules-for-screen-controls#validation-rule-settings), and then locate the validation rule for its parameters.

Follow these steps to delete a validation rule for this control:

1. Access the [**Variable** panel for this control](/v1/docs/bootstrap-component-control#variable-panel-settings) while in Design mode, and then locate the **Validation Rules** setting.
2. Click the **Delete** icon![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/762adb47-8b68-457b-949b-f5f2b8b552ad.png)for the validation rule to delete. A message displays to confirm deletion of the validation rule.
3. Click **Delete**.

#### Make Required

Select to indicate that this control is required. This option is not selected by default. This is a quick way to add the [Required](/v1/docs/validation-rules-for-screen-controls#required) validation rule.

In the Screen preview or during a Request if you submit the Screen without selecting this required Bootstrap Component control, this control displays **Field is required** in red-colored text.

### Configuration Panel Settings

Expand the **Configuration** panel from the Properties Panel on the right to configure the following properties:

#### BootstrapVue Component

In the **Bootstrap vue component** setting, select one of the following BootstrapVue components ProcessMaker Platform supports. The following hyperlinks reference BootstrapVue documentation for their descriptions:

- [Embed](https://bootstrap-vue.org/docs/components/embed)
- [Image](https://bootstrap-vue.org/docs/components/image)
- [Form Rating](https://bootstrap-vue.org/docs/components/form-rating)
- [Form Spinbutton](https://bootstrap-vue.org/docs/components/form-spinbutton)
- [Form Tags](https://bootstrap-vue.org/docs/components/form-tags)
- [Form Timepicker](https://bootstrap-vue.org/docs/components/form-timepicker)
- [Table](https://bootstrap-vue.org/docs/components/table)

The **Form Tags** setting is selected by default.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/e1b22cb7-6aac-4b4c-b5d9-bbb8cc849afa.png)

#### Component Configuration

In the **Config** setting, enter component BootstrapVue properties in JSON format.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/a24033ec-7c3d-45ae-9022-45cd1fbda774.png)

Refer to the following BootstrapVue documentation for property descriptions for each available component:

- [Embed](https://bootstrap-vue.org/docs/components/embed#comp-ref-b-embed-props)
- [Image](https://bootstrap-vue.org/docs/components/image#comp-ref-b-img-props)
- [Form Rating](https://bootstrap-vue.org/docs/components/form-rating#comp-ref-b-form-rating-props)
- [Form Spinbutton](https://bootstrap-vue.org/docs/components/form-spinbutton#comp-ref-b-form-spinbutton-props)
- [Form Tags](https://bootstrap-vue.org/docs/components/form-tags#comp-ref-b-form-tags-props)
- [Form Timepicker](https://bootstrap-vue.org/docs/components/form-timepicker#comp-ref-b-form-timepicker-props)
- [Table](https://bootstrap-vue.org/docs/components/table#comp-ref-b-table-props)

### Example

If using an image component, use the property `src` and `fluid`:

```plaintext
{
     "src":"https://picsum.photos/1024/400/?image=41",
     "fluid":"true"
}
```

---

### Advanced Panel Settings

Expand the **Advanced** panel from the Properties Panel on the right to configure the following properties:

#### Visibility Rule

Specify an expression that indicates the condition(s) under which this control displays. See [Expression Syntax Components](/v1/docs/feel-expression-syntax#show-or-hide-screen-builder-controls). If this setting does not have an expression, then this control displays by default.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/d98cc3c2-31ad-4583-9e34-b377b6027d83.png)

For example, this control displays if the variable value **tip** is **1**. For a detailed example of the Visibility Rule setting, see [Show or Hide Controls Based on Button Selection](/v1/docs/example-show-or-hide-controls-based-on-button-selection).

Note the following regarding how to use visibility rules:

- To make this control hidden until another control contains a value, enter the **Variable Name** setting value of that control to this control's **Visibility Rule** setting.
- [Visibility rules override custom CSS settings](/v1/docs/screen-design-best-practices#visibility-rules-override-custom-css-settings).

#### Device Visibility

Select on which device types this control displays:

- **Desktop:** The control displays only on desktop devices. Enable the **Show for Desktop** toggle key.
- **Mobile:** The control displays only on mobile devices. Enable the **Show for Mobile** toggle key.
- **Both:** The control displays on both desktop and mobile devices. Both toggle keys are enabled by default.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/5688acfc-fd12-497c-99c6-769655f4500d.png)

#### CSS Selector Name

Enter the value to represent this control in custom CSS syntax when in [Custom CSS](/v1/docs/custom-css#add-custom-css-to-a-processmaker-screen) mode. As a best practice, use the same **CSS Selector Name** value on different controls of the same type to apply the same custom CSS style to all those controls.

![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/1aa0b439-45c0-4f43-8018-04eaa2fa788c.png)

Then, use this name in the [Custom CSS](/v1/docs/custom-css#apply-css-to-specific-processmaker-screen-controls) feature to apply CSS styling to this control as follows:

```plaintext
[selector='Submit Form'] {
    color: blueviolet;
}
```

See the following best practices regarding custom CSS in Screens:

- [Editing a CSS name to represent this control in custom CSS syntax](/v1/docs/screen-design-best-practices#css-selector-naming-best-practice)
- [Visibility rules override custom CSS settings](/v1/docs/screen-design-best-practices#visibility-rules-override-custom-css-settings)
